Transport - Dac , matching question.

This is somewhat of a dizzy question, but here goes. Just a small bit of theory first. Dacs use software that operate in two different domains, probably more accurate , in a combination of these domains. These being time and frequency.Time domain dacs use steaper rolloffs in their filtering in contrast to their counterparts who have a lot gentler rolloffs. Krell and wadia are two good examples of cdp that filter in the time domain. Meridian and musical fidelity tend to use upsampling and thus have a more gentler rolloff. My question is - when matching transports to dacs - are there any trademarks in transport designs by particular manufactures, whose filtering philosphies come into the picture, that tend to match better with dacs with the same filtering techniques. For example; maybe matching a krell transport with a wadia dac is ok but matching a krell with a meridian you might lose some musical symmetry.
Any comments or technical insight would be appreciated, or corrections to my understanding is also invited.
